Be it known. that I, THOMAS SLOPER, a

'subjectof't hefKing of England, residing at Devize's', Wiltshire, England, have invented certain new and. useful Improvements in Manufacture of "Articles Buil't Up. from Lengths offCOrd, of which the following is.

This-inventionflis for improvements in .or. relating \to the manufacture of .articles or 'fab ric built up from lengths of rubber-ed. cord 'or other material and has for its object' toprovide better anchoring means for the lengths of material that are used or that are uilt together. r

[Asis well known in building up an article or'fabric from lengths offmaterial for examplerubbered cord, which maybe composed of asingle lengthof cord doubled backward and forward upon itself, so that it provides a series of lengths laid side by side, it is often required to secure those portions which formth'e edge of the article or.

. fabrictogether by some form 'of anchoring :Ineans. Among othermetliods this securing has beforebee'neifected by sewing or 'by metal staples or, pins around which the lengths of cord were passed and which staples or pins were afterward secured in an edging. According to one-.method, for

example, if building a tire from rubbered [cord the length of cord was bentbackward and'forward around pins or staples detachably carried by a suitable former and -after the tire had been thusbuilt up, the

fabric with the pins or staples or it was removed from the former and beads" were 'built on to the pins or staples so that a secure anchorage was afforded for all the cient s'trength to take the place of the Wire co'mmonly inserted in the edge of the cover, it may be made to carry the wlre. The anchoring member may further be so con-f imbted that it is itself inextensible. but

flexible'in one or more directions, or it may be both flexible and extensible. In the accompanying drawings, which illustrate various forms of anchoring mem- 'is aside elevationof a strip or ring provided with lateral claws'or projections; Fig.

the method 'of bringing the parts illustrated 0 Like letters indicate like parts throughare-shown as stamped up from a strip orfii'o length of material of which the tire is tobe built, may be then bent around each ofthe pins A in turn and carried backward and forward over the former according to usual practice, the pins' or claws A taking the place of the separate detachable pins .15 heretofore employed with such formers.

The pins or projections A, together with the strips or rings A are thus built into the tire and whole can afterward be.vu1- canized together. That portion of the ring that lies between the pins and the center may be employed to carry a bead or may be itself bent around to-form a bead, as found convenient. In Fig. 1, the three claws or projections on the left hand side areshown as only broken away from the main body of i the strip, but not bent up into position, and

the two claws on the right hand side are shown in section close to the root of the claw. Each claw is tapered and is made trough-shaped, as is clearly shown, to give .it increased strength,

In Figs. 4 to 6, a strip or ring B is shown having claws B stamped up from its edge.

In Fig. 7 a method is shown of inclosing a wire C-by the anchoring strip or ring that is built into the tire. The strip or ring D for this purpose is built up of a number of. sections one of which is shown in the vfiat in Fig. 9. Each of said sections. or blanks 140 is provided with claws D at one edge and near the opposite edge are orifices D corre 'sponding to the claws. Before the cords of the fabric are placed over the claws D the latterare bent up at an angle to' the body I of the blank and the blank is bent, for ex ample, into the form shown in Fig. 7 to receive the endless wire C. After the cords have been engaged with the claws and the wire C positioned as shown in Fig. 7, the

bodyof the section or blank is further bent upon itself around the wire 0, so that it is made to takethe shapeshown in Fig. 8, the ends of the claws D projecting into the holes D I Fig.30 illustrates a wheel rim carrying a tire provided with anchoring strips 0 above described. This rim is of ..,well-known constructionandcomprises endless rings K, K

i that .keep-the tire in place and a further endless ring: L that is sprung into a recess M in the rim and keeps the ring K from beingdisplaced. j .In Figs. 11 to 13, a str p or plate eonstituting one f a number of sections is shown having claws E at each edge. One

edge of this strip is folded over upon the other, so thatthe claws-face. each other, those of one side receiving one layerof cord and those on the other edge receiving the other layer as shown in Fig. 12.

If it is desired to render the anchoring member flexible, the main body of the strip or ring may be cut away, as shown in Figs. 14 to 16, so'that only a skeleton plate F isleft of wavy construction having claws'F at '75 the crests of the waves or undulations. This, is easily stamped from the flat, as will be seen, one claw being shown extended in the fiat prior to its being bent into position at right angles to the main body of the strip. This anchoring member would be flexiblelaltiarallyand would also be slightly exten- S]. e."

Another form of strip or ring giving greater flexiblity and also increased extensibility is shown in Figs. 17 to 19. This can be stamped from a strip of flat material, the 1 plane of which would be the same as that occupied by the claws when finished, the body of the material being corrugated be- 9 tween the claws to give the desired flexibil-v ity and extensibility.

In F igs. 20 to 22 a strip is shown that is narrowin its transverse dimensions, so that it has lateral flexibility, but is inextensible owing to the body of the strip lying all in one line.

ltzwill' be seen that in 1.1 to 13,-the anchoring member forms an inclosing casing for the edge of the tire and constitutes a metallicbead having within it the inextensible wire. If desired, the casing effect may be obtained by making'the anchoringmember'in two parts, whereof one is a U-shaped strip or ring G having pins or claws G at 1 5 both edges which extend laterally from the ring,as shown inFigs. 23, 24 and The cords of the fabric are fastened around the elawsGand then a trough-shaped member H which may be in the form of an endless ring or in sections forming parts of a ring, is bent around the edge of the tire and locked overthe ends of the claws, the trough or casing member H having inwardly turned edges H for the purpose ofengaging the pins and holding the casing member in place.

4 In Fig. 25 the trough-shaped member is 'shown ready for bending over the edge of the fabricand the pins Insome cases it may be desired to make the main body of the strip or ring of sufficient dimensions and sufficiently stout to enable it vto be bolted direct to the road-wheel whereon the tire is to be employed, so that 1 the anchoring member constitutes the direct connection between the tire and the wheel instead of the edges of the tire being held in a rim orbetween separate flanges secured to the wheel. This construction would be par- Studs J 3 mg portlon of the striponring and that can be bent, back I 1168 the claws.
